General description.

This invention is shown embodied in a machine adapted to be used in railroad ticket ofiiccs or the like to issue local tickets. It is evident that it could be used in a large number of places where tickets are issued and therefore it is to be understood that no limitation of the invention to the mechanism shown herein is contemplated.

The machine shown herein comprises an operating mechanism and a plurality of ticket printing units, the number of which may be varied in accordance with the size of the station and the number of destination points to which local tickets are issued. Each of the ticket printing units is adapted to issue either one way or round trip tickets, the change from one to the other being effected by a manually movable lever.

Only one unit can be operated at a time and therefore the operating mechanism can be the same, no matter how many units are incorporated in the machine.

All of the units have-electrorollers which are adapted to print the same data, this data being of an invariable nature, such for instance as the name of the railroad. The date is printed by separate type wheels, all of which are simultaneously adjusted by a single means.

The variable portion of the data printed on each ticket is printed by a plurality of detachable destination devices. There is one of these devices provided for each station to which alocal ticket may be issued. Each of the devices carries two electroplates, one for printing the name of the station and the other for printing the price of the ticket.

In addition, each of said devices carries a consecutive number counter which prints the consecutive number on each ticket. Means are provided for advancing this counter one step1 on each operation in which the device is use Shortly before a train is due, the ticket agent will insert into the machine a plurality of the destination devices. The devices selected correspond to the points on the route of the approaching train to which he may be called upon to sell local tickets. One unit is usually reserved so that the destination device for any other station can be inserted if such a ticket is called for.

The machine is so organized th.t the devices may be partially inserted into the issuing units where they will be latched in vice to its printing position, where it is locked, and at the same time actuates mechanism to release the operating mechanism and thereupon operate the machine to issue the desired ticket. At the end of the operation the destination device will be returned to its partly inserted condition. The destination devices may be removed at any time and others substituted therefor.

A grand total consecutive number counter is provided which will add 1 whenever any of the units is operated, thereby furnishing the company with a check on the number of tickets sold. The amount on this counter will equal the total of the amounts on all of the destination devices.

The destination devices are provided with means which must be properly adjusted before the machine is operated or the consecutive number adding wheels will be prevented from turning.

If a round trip ticket is desired, the operator moves a control lever to its round trip position. This movement adjusts the mechanism so that the machine will operate twice. On one way operations, one of the electrorollers carries type which print the words From and To in connection with the name of the issuing station. The movement of the round trip lever will position mechanism to change the adjustment of these type wheels after the first impression has been made so that on the return portion of the ticket the wording will be reversed. That is, the wording will read, as shown in Fig. 3, To Dayton from Lima. It is therefore a very simple matter to issue a round trip ticket.

Mechanism is also shown which enables this machine to be used to issue tickets for theaters, amusement parks, andthe like. This mechanism simply controls the number of tickets which may be issued at one operation by controlling the number of cycles of operation. As many insertable devices are used as there are prices of admission and these are left in the machine unless a change of prices is made.

Means are also provided for locking the insertable devices in the machine or looking the machine against the insertion of any devices.

Destination devices.

The detachable destination devices, which release the machine for operation and print the variable portion of the data on the issued tickets, will be described first. These devices are shown in detail in Figs. 9 to 13,

inclusive. Each device consists of a metal box 30, which encloses all the mechanism and which has an opening 31 in the bottom through which a plurality of consecutive number printing wheels 32 project. These wheels are all loosely mounted on a shaft 33 supported by the side members of the box 30. Fast to the units consecutive number type wheel is a gear 34 with which a gear 35 suported by a transverse shaft 36 meshes. *ast to the gear v35 is a ratchet wheel 37 (Figs. 10 and 13) with which a feedin pawl 38 cooperates. This pawl is pivote von a member 39 which is loosely mounted on the shaft 36. A torsion spring 40 constantly tends to rock the pawl 38 counter-clockwise and thereby holds it in engagement with the teeth of the ratchet wheel 37. Fig. 13 shows the above described parts in the positions for one side of a which they normally occupy. A link 41 (Fig. 13) carries a pin 42 WhlCll is normally just outside of an opening'43 in the back of the box 30. During the operation of the machine this link 41 will be moved to the left, as seen in Fig. 10, and then returned by mechanism which will be later describe and the pin 42 will come into contact with the upper end of the member 39 and will rock this member and the pawl 38 counterclockwise to the position seen in F i 10. As the pawl is 1n engagement wit the ratchet wheel, this wheel will be carried one step in a counter-clockwise direction. As the gear 35 is fast to the ratchet 37 this gear and the gear 34 with which it meshes will also be rotated one step in order to add 1 on the cdnsecutive number counter. The pawl 38 will be returned to its normal position (Fig. 13) by the movement of link 42 to the right as will be later described, and upon this movement the pin carried by this link will strike a projectlon 44 of the member 39 and return the pawl 38 to its normal osition. The means for transferring From lower to higher orders in the destination device consecutive number counter is the well known Geneva transfer mechanism which, due to its antiquit it isbelieved to be unnecessary to descri herein.

, It is necessary to prevent movement of the consecutive number type ,wheels while the destination devices are out of the machine, and the following mechanism is provided to accomplish this object. Meshing with the gear 35 (Figs. 11 and 13) is an arm 45 loosely mounted. on a transverse shaft 46 (Fig. 12) supported by the side members of the box 30. This arm 45 forms the support yoke 47 which at its. opposite side is su iported by an arm 48. A torsion spring ig. 1.3) coo crates with the yoke 47 and constantly ten 5 to rock it in a counter-clockwise direction. Four slides 49 (see also Fig. 1) are provided, each of said slides having a notch, 50 which, under certain conditions, is adapted to cooperate with the yoke 47. These slides are normally held in their farthest position to the right, as shown in Figs. 12 and 13, by means of torsion springs 51 which are wound around theshaft 46 and their ends passed through holes in the slides 49. Movement of these slides toward the right is limited by shoulders formed thereon which cooperate with the inside of the back plate of the box 30.

From the above it is evident that, with the slides 49 in the positions which'they occupy when the devices are detached from the machine, the yoke member will be held up on top of the slides and will not be permitted to move down into the notch 50. This position of the yoke will cause the arm 45 to engage with the teeth of the gear 35 and lock this gear and the consecutive number type wheels 32 against any movement while the device is out of the machine.

Means are provided for releasing the arm 45 from its engagement with'the gear '35 to permit the consecutive number type wheels to be rotated, when a device is inserted into the machine. i

As shown in Fig. 8, each receptacle for the destination devices has four ears 52 struck up from its lower side. These ears are of different heights, each ear corresponding to a particular one of the slides 49. The length of these slides also varies and the arrangement is such that only the devices appropriate to any particular machine can be operated by the particular combination of ears found in that machine. That is, itis necessary that the slides 49 be moved difierent distances in order to position the notches 5O beneath the yoke 47 and the correct positioning of these slides can only be effected by the particular earsfound in the appropriate machine. This mechanism is provided to prevent manipulation of the destination dfivices when they are removed from the mac me.

Receptacle for distinction devices.

It may be said here that the present machine is composed of an operating mechanism, a variable number of ticket issuing units and controlling mechanism. The units are duplicates of each other and therefore only one of them will be described herein. It is possible to provide as many units as may be necessary in the particular ticket oflice in which the machine is to be used, as only one of the units can be operated at a. time and therefore the same operating mechanism can be used. Before a train arrives at a station at which one of the present machines is in use the operator will insert into the various units the destination devices corresponding to the Various points on the route of the approaching train to which he may be called on to sell tickets. When one of the devices is inserted into a receptacle, pins 60 (Figs. 1 and 2) projecting from opposite sides of the destination device enter notches 61 in the upper ends of arms 62 pinned on a shaft 68 sup orted by the frames 65. There are two 0 these arms 62 for each of the ticket issuing units and each of the arms is adapted to receive one of the pins 60 projecting from each side of the destination device inserted. The arms 62 are normally'held in their upper positions, in which they are adapted Ito receive the pins 60, by means of a spring 64 (Fig. 2) stretched between a pin on the arm 62 and a pin on a frame 65 which forms a support for the destination device when it is in the machine. The plate 65 has extensions 66 which have slots formed therein adapted to cooperate with the pins 60 of the inserted destination devices and help to support and guide them.

Fast to the left hand one of the pair of arms 62 appropriate to each of the ticket issuing units is a lever 67 (Fig. 2). This lever has arearwardly extending arm 68 which at its extreme end has a wedgeshaped portion cooperating with two of a plurality of pivoted plates 69 supported by a frame 70. The function of these plates is old and well known, said function being to prevent more than one of the destination devices from being operated at the same time. The lever 67 has another arm 71 which carries a flattened stud 72 projecting through a slot 78 formed in a member 74 loosely mounted on a shaft 7 5. Also loosely mounted on a transverse shaft 76 is a bell crank lever 77, the right hand arm of which as seen in Fig. 2, cooperates with the pin 72. he left hand arm of this bell crank lever 77 contacts with a rod 78 carried by an arm 79 and an arm 170 (Fig. 1) pinned to a shaft 80 supported by the machine side frames. A spring 81 (Fig. 2) attached to the left hand arm of the bell crank 77 constantly tends to rock this bell crank lever in a clockwise direction, but. it is normally prevented from effecting this movement because the pin 72 lies in the path of the right hand arm of the bell crank 77. Also fast on the shaft 80 is an arm 82 (Figs. 14 and 15 the end of which cooperates with a fiattened pin 83 carried by an arm 8&fast on a shaft 85. This shaft 85 also has fast thereon an arm 86 which has its end bent upwardly to cooperate with a plate 87 fastened to a clutch member 88. The clutch mechanism is only partially shown herein, as that used is very well known and is only illustrative. Any desired form of motive power may be used. If any further description of the clutch mechanism is desired it may be found in the patent to Kettering No. 923,857, issued June 8, 1909. The clutch member 88 constantly tends to rotate in a clockwise direction due to a torsion .of the destination device.

sprin 89 which cooperates therewith and is on y prevented from this movement by the upper end of the arm 86. When this arm is removed the clutch member will rotate and connect the motor to a shaft 90 which is the main drive shaft of the machine. A spring 91 (Fig. 15) constantly tends to remove the arm 86 from engagement with the clutch member 87, but the arm 86 is held in the position shown in Fig. 15 due to the engagement of the pin 83 with the arm 82.

When it is desired to issue a ticket from any particular unit the destination device appropriate to the destination for which the ticket is sold is pushed inward. This movement is made more convenient for the operator by having 'a key 95 projecting from the upper end of each destination device. This key bears on its face the name of the station to which it is appropriate in order to facilitate the operation of the machine. When this key and the destination device attached thereto are pressed inwardly the lugs 60 will cooperate with the slots 61 and rock the arms 62 and the member 67 in a counter-clockwise direction to a sufficientextent that the flattened pin 72 will pass out from under the right hand arm of the bell crank lever 77 (Fig. 2). When this occurs, the bell crank lever 77 will be rocked clockwise by the spring 81 and will rock the arm 79 and shaft 80 also clockwise a sufficient distance to remove the arm 82 (Fig. 15) from its engagement with the flattened pin 83 carried by the arm 84, which will then be free to rock clockwise. This movement will be accomplished by the spring 91 acting on the arm 86 and therefore this arm 86 will be removed from in front of the plate 87 on the clutch member 88. The clutch member is then free to rotate under the influence of the spring 89 to close the motor circuit and connect the motor to the drive shaft 90.

In Fig. 2 the destination device is shown in the position in which it is held between operations of the machine. When the dewoe is removed from the machine the pin 72 moves up into theupper end of the slot 73. It can be seen that the right hand arm of the bell crank lever 77 has a round projection thereon which cooperates with the pin 72 and is adapted to flexibly hold the mechanism in one or the other of the positions When the machine is to be released and a ticket issued, the destination device is pushed all the way down, as above mentioned. This movement causes the pin 72 to be moved down into the lower end of the slot 73, which, due to the shape of the slot, will rock the member 7 1 clockwise. The member 74 has a downwardly extending arm 96 (Fig. 2), which carries a broad pinion 97. This pinion is adapted to cooperate with a pair of gears tion on every operation. When a particular unit is selected for operation, the gear 98 appropriate thereto is coupled to the gear 99 by means of the broad pinion 97, and therefore the gear 98 and the mechanism of the unit is'operated. As only one destination device can be depressed during an.

operation it is evident that only one pair of the gears 98 and 99 will be coupled together, the remainder of the gears 99 running idle. From the gear 98 all of the ticket issuing mechanism of the particular unit selected is driven, and this mechanism will now be described. While the pinion 97 is out of engagement with the gear 98 any movement of this gear is prevented.

' Fast to this gear is a disk 100 in which a notch 101 (Fig. 2) is formed. A pin 102 carried by the member 74 normally engages in this notch and prevents any movement of the gear 98 or the mechanism connected therewith.

The tickets are stored in the form of a roll which is supported on a rod 110 (Fig. 7) supported beneath the machine by brackets 111. There is, of course, one of the rolls of paper appropriate to each of the ticket issuing devices. From the storage roll the ticket strip passed upwardly and through a chute 112.. From the chute 112 the strip passes between an electroroller 113 and an impression roller 114 of any suitable material. From the lower electroroller the strip passed, upwardly over a platen 115 and a laten 116, which will be described later, then between amovable knife 117 and a stationary knife 118, and finally between an electroroller 119 and an impression roller 120. It is then fed to an opening 121 in the top of the machine, from which position. it may be removed by the purchaser.

Feeding and electrorollers. The lower feeding and electrorollers will The described first. It is evident from Fig. 2

that when the gear 98 is rotated as above described, the movement will be transmitted to a gear 122 clutched to the end of a sleeve loose on the shaft 75. Also clutched to this sleeve is a gear 134 which in turn meshes with a gear 123 (Fig. 7) loose on a shaft 124 which extends transversely of the machine. Fast on the sleeve which joins the gear 122 and gear 134 is the impression roller 114. It can be seen from Fig. 2 that this roller will be rotated in a counter-clockwise direction. Fast on the gear 123 is the electroroller 113. This roller carries feeding rails 125 which cooperate with the impression roller to feed the ticket strip. It

plates which are adapted to print the in variable data, such as the name of the issuing station and the name of the railroad, on the face of the ticket (see Figs. 3, 4 and 17).

The feeding roller 119 carries feeding rails 126 and cooperates with the impression roller 120 to feed the ticket strip after it has been severed, as will behereinafter described. The roller 119 also carries an electroplate which is adapted to print any desired data on the back of the ticket. This roller is loosely mounted on the shaft 76 and is fast to a gear 127 (Fig. 2) which meshes with 'the gear 98 above described. It can therefore be seen that the clockwise movement of the gear 98 will rotate the gear 127 and the feeding roller 119 counterclockwise in order to feed the ticket.

The electroplate for the feeding roller 113 is inked by an inking roller 128 (Figs. 1 and 7), which is made of felt or any other suitable material and which is carried on a rod 129 supported by a mounted on a rod 131. The inking roller is held in contact with the electroplates by means of a spring 132. A mechanism identical with that just above described is provided for inking the upper electroroller 119 and it is not thought to be necessary to give a detailed description thereof.

Mechanism for taking an impression from g the destination device. The means for taking an impression from the destination device electroplates, as well as the date type wheels. will now be described. As shown in Fig. 7, there is a pair of arms 130 loosely and also the platen 115 which is for the purpose of taking an impression from the date type wheels. The means for operating the platens 116 and 115 consists of a cam 142 (see also Fig. 1) fast on a sleeve 143 which is integral with the gear 98 and surrounds the shaft 90. The periphery of the cam 142 cooperates with a roller 144 carried by the platen carrying member 140. It is evident that when the gear 98 is rotated the cam 142 will also be rotated in a clockwise direction. The timing of the cam 142 is such that the impression will be takenfrom the plate destination device and from the date type wheels immediately upon the operation 0 the machine, the invariable data printed by the lower electroroller 113 having been printed at the last previous operation.

Seoem'ng mechanism.

WV-hen a one way ticket is to be issued the ticket is severed from the ticket strip near the end of the operation. The severing mechanism comprises the movable knife 117 (Fig. 7) and the stationary knife 118. The movable knife 117 has an opening therein through which the ticket strip passes when the knife is in its normal position. The knife is slidably mounted in a uideway 150 which is supported by the machine frame and the knife is connected to the platen carryin member 140 by means of two upwar ly extending members 151 which ex tend into openings (see also Fig. 1) in the movable knife. The stationary knife is held in contact with the movable knife by means of a spring 152 which is stretched between a rod supported by the side frames of the machine and the end of an arm 153 fast to a member 154 to which the stationary knife is riveted. \Vhen the platen carrying member rocks clockwise to take an impression, the movable knife is slid upwardly, but this movement has no effect, as the opening in the knife is sufliciently large to permit this movement. Near the end of the operation, however, a earn 155 which is also fast on the sleeve 143 comes into contact with a roller 156 carried by an arm 157 which is loosely mounted on the shaft 141 and rocks this arm counter-clockwise and then clockwise to its normal position. The arm 157 has a slot cut therein through which a pin 158 pro jects. The pin 158 is carried by an arm 159 which is pivoted to the upper end of a lever 160 fast on a shaft 161 which extends completely across the machine. A notched 162 is riveted to the platen carrying member 140 in such a position that the notch normally engages with the pin 158. It can be seen from Fig. 7 that with the parts in the positions shown in this figure the movement of the arm 157 in a counter-clockwise direction will, through the pin 158 and plate 162. lower the platen carrying member 140 a sufficient distance to cause the movable knife 117 to sever the ticket strip.

Means for restoring release mechanism on one way operatzons.

Near the end of the operation of the machine it is necessary to restore the release mechanism to its normalposition, as shown in Figs. 14 and 15. The mechanism for secomplishing thisresult is as follows: It will be recalled that when the selected one of the destination devices is pressed inwardly the shaft will be rocked clockwise far enough to remove the end of the arm 82 f from in front of the flattened stud 83 carried by arm 84. Near the end of the op eration of the machine mechanism which will be presently described rocks the shaft 80 counter-clockwise to its normal position. The lower edge of the arm 82 (Figs. 14 and 15) is inclined with relation to the flattened stud 83 so that as the arm 82 is rocked counter-clockwise to normal a camming action will result which will rock the arm 84 and the arm 86 counter-clockwise to their normal positions. When the arm 86 is moved into its normal position the upwardly extending portion thereof is brought into the path of the plate 87 on the clutch member 88 so that when this plate comes into contact with the arm 86 the clutch will be broken and the driving connection with the motor will therefore be rendered ineffective.

The means for restoring the arm 82 and shaft 80 to their normal positions is as fol lows: Fast on the shaft 80 is an arm 170 (Fig. 14) connected by a link 171 to an arnr 172 (Figs. 14 and 16) loose on a shaft 173 supported by the machine side frames. Also fast on the shaft 173 is a bell crank 174, the left hand arm of which rests on the pin which connects the arm 172 and link 171. The other arm of the bell crank has a bent end 175. When the shaft 80 and arm 82 are rocked clockwise, as above described, to release the machine, that through the arm 170, link 171 and arm 172 the shaft 173 and bell crank 174 will also be rocked. The movement of these parts is limited by the engagement of the bent end 175 of the bell crank 174 coming into contact with a bent portion 176 formed on a lever 177 which is pivotally mounted on a stud 178 supported by the machine side frame. The lever 177 has an upwardly extending portion 179 which passes through an opening in the cabinet of the machine in a convenient position to be manipulated by the operator. The further functions of this lever will be presently described.

Before the shaft 173 can be rocked clockwise another mechanism is operated, which will now be described. Fast on the shaft 173 is a ratchet wheel 180 with which the end of an arm 181 (Fig. 14) cooperates. This ratchet wheel is so designed that the arm 181 will prevent rotation of the wheel and therefore movement of the shaft 173, arm 172, link 171, arm 170 and shaft 80 until the arm 181 is moved out of engagement with the ratchet. This disengagement of the arm from the ratchet is accomplished automatically in the following manner. The member 74 (Fig. 2) which is rocked clockwise to couple the driving gears of the unit to be operated by the depression of the selected destination device has a downward- 1y extending member 183 which lies just toit is evident manner.

the right of a yoke member 184 which is loosely mounted on the shaft 75 and which extends across the entire machine beneath all of the ticket issuing units. Near the right hand side of the machine, as'seen in Figs. 1 and 14, the yoke member 184 has integral therewith an arm 185 to which is ivoted a pawl 186, the lower end of whic is hooked beneath a flattened stud 187 carried by the arm 181. The pawl 186 is held in engagement with the stud 187 by means of a spring 188 stretched between a pin on the upper end of the pawl and a pin carried by a projection of the arm 181.

It can be seen from the above that wheni ever any of the destination devices are depressed and the member 74 corresponding thereto is rocked clockwise, the downwardly extending mm 183 of the selected member 74 will engage the yoke member 184 and rock it slightly clockwise far enough to cause the pawl 186 to raise the arm 181 out of engagement from the ratchet wheel 180 in order to permit the shaft and the parts above de scribed to be operated by a torsion spring 195 (Fig. 1) wound about the shaft. The yoke member 184 will of course be held in its moved position until the broad pinion 97 is moved out of engagement with the gears 98 and 99 at the end of the operation, but as the shaft 17 3 and the parts thereon are restored to their normal positions prior to the disengagement of these parts it is necessary to disconnect the pawl 186 from the pin 187 and permit the arm 181 to drop down into contact with the ratchet wheel in order to hold the parts in their normal position as they are restored. In order to accomplish this, a disk 189 is fast to the main drive shaft 90 and is rotated in a clockwise direction (Fig. 14) with said shaft. This disk carries a pin 190, which as the disk rotates will come into contact with a surface 191 on the upper end of the pawl 186, and due to the inclination of this surface will cause the pawl 186 to rock counter-clockwise far enough to disengage its lower end from the stud 187 on arm 181, thereby permitting this arm to drop under the influence of the spring 188 and of gravity.

With the lever 177 in the position shown in Fi 14 the mechanism will issue a one way ticket. It has already been described how, when the machine is released, the bent end 175 of the bell crank 174 will come into contact with the bent portion 176 of the lever 177. Near the end of the operation it is necessary of course to restore this bell crank and the mechanism connectedthere-to to its normal positions, as seen in Fig. 14, and this is .accomplished in the following Also fast on the shaft 173 is a member 192 which is rocked clockwise with the other parts when the machine is released. This member has a projection 193 which in its moved position lies in the path of the pin 190 carried by the disk'189, and

as this disk rotates in a'clockwise direction.

they will be held by the engagement of the am 181 with the ratchet wheel 180.

Round trip operation.

When a round trip ticket is to be issued the operator moves the upper end of the lever 179 to the right, as seen in Fig. 14. This movement of the lever will raise the bent portion 17 6 thereof upward out of the path of the bent end 175 of the bell crank 174 and therefore when the arm 82 is-moved out of engagement with the stud 83 by the depression of the selected destination device the shaft 17 3 is rocked clockwise, as in a one way operation, but due to the fact that the bent portions of the lever 17 7 and bell crank 174 are out of alinement, the movement of the shaft will be continued until a projection 194 of the member 192 comes into engagement with the bent portion 176 of the lever 177 and stops the movement of the shaft 173 and its associated parts. The

shaft 173 is rocked by means of a torsion spring 195 (Fig. 1) which is wrapped around the right hand end thereof.

On round trip ticket issuing operations the mechanism is, of course, given two cycles of movement. When the pin 190 carried by the disk 189 makes its'first rotation it will come in contact with a projection 196 of the member 192 which has been moved into its path, and through its engagement with this projection will rock the shaft 17 3 and its associated parts approximately half of the dis tance to their normal positions, where they Wlll be held by the arm 181 which has been permitted to come into contact with the ratchet wheel 180 due to the tripping of the pawl 186 by the pin 190. Then on the second rotation of the disk 189 the pin 190 will engage with the projection 193 above described in connection with one way ticket issuing operations and will return the shaft 17 3 to its normal position.

Control of severing mechanism.

It is not desired to' have the severing mechanism effective to sever the ticket on the first cyce of a round trip ticket issuing operation, and mechanism is therefore provided for disabling this mechanism on the first cycle of operation. Fast on the shaft 173 appropriate to each of the ticket issuing units is a cam 200 (Fig. 7) which cooperates with a roller 201 carried by the arm previously described. It will be recalled that the arm 160 carries a link 159 which in turn carries a pin 158 normally lying in the notch ofthe plate 162 which is secured to the platen carrying member 140. So long as the pin 158 remains in the notch in plate 162 the knife for severing the tickets will be operated. Fast on the shaft 161 is a downwardly extending arm 202 to the end of which is fastened one end of a spring 203 secured at its opposite end to the pin on the frame. This spring tends constantly to rock the shaft 161 and arms 160 to remove the in 158 from the notch in the plate 162, but this action is normally prevented by the engagement of the roller 201 with the raised portion of the cam 200 appropriate thereto. When a one way ticket is issued the shaft 173 rocks only a short distance in a clockwise direction and the cam 200 hasa concentric portion which holds the pin 158 in engagement with the notch in the plate 162 during one way ticket issuing operations. When, however, a round trip ticket is to be issued, the shaft 17 3 moves clockwise to a greater extent and far enough to bring the low portion of the cam 200 into contact with the roller 201, thereby permitting the arm 160 to rock clockwise under the influence of the s ring 203. This movement of the arm will disengage the pin 158 from the notch in the plate 160 and upon the operation of the arm 157 by the severing cam 155 there will be no movement given to the platen carrying -member 14.0 to sever the ticket at the end of the-first cycle of operation.

It will be recalled that the shaft 173 is returned in a counter-clockwise direction about half way to its normal position at the end of the first cycle of operation, and this movement will bring the high portion of the cam once more in contact with the roller 201 and the arm 160 will be rocked clockwise to re-engage the pin 158 with the notch in the plate 162, and therefore upon the second operation of the severing cam the platen carrying member 140 will be moved counterclockwise to sever the ticket at the end of the second cycle of operation.

-Means for driving and disabling the destination device conseentioe number operatzng mechanism.-

It will be recalledthat the consecutive number counter of the selected destination device is operated by the movement of the arm 41, as above described. This arm is pivoted to a bell crank lever 205 (Fig. 8) which is loosely mounted on the shaft 141. The arm il'is held in its normal disengaged position by means of a spring 206 extending between a pin on the bell crank lever 205 and a pin on the frame. The left hand arm of the. bell crank lever 205 has a slotted end the above quoted phrase.

207 through which a pin 208 carried by a link 209 projects. This link is pivoted to the arm 160 fast on the shaft 161, it being understood that there is one of these arms and the corresponding mechanism provided for each ticket issuin unit. It will be recalled from the description of the severing mechanism just above given that the arm 160 is held in the position shown in Fig. 8 by means of the cam 200, which is fast on the shaft 173. Loosely mounted on the shaft 1 11 is an arm 210 having a notch in which the pin 208 normally rests. The arm 210 also carries a roller 211 which projects into a cam slot 212 formed in the side of the gear 122 appropriate to each of the units. The gear 122 is given one compete counterclockwise rotation on each operation of the machine and the configuration of the cam groove 212 is such that the arm 210 will be rocked counter-clockwise and then clockwise to its normal position. The movement of the arm 210 will be transmitted to the bell crank lever 205 and through it to the arm 41 by means of the pin 208 which normally engages in the notch in arm 210 and therefore the consecutive number operating mechanism will be advanced one space on each one way ticket issuing operation. When, however, a round trip ticket is to be issued thecam 200 will be rocked far enough, as above described, to bring the low portion thereof into contact with the roller 201 on lever 160 and thereby this lever will rock counter-clockwise and will withdraw the pin 208 from the notch in the arm 210. Then when the arm 210 is rocked by the'cam groove 212 it will have no effect on the consecutive number operating mechanism and the same consecutive number will be ticket.

Method of changing adjustment of type on roan trip operations.

printed on both parts of the round trip of the ticket should read the same as a one way ticket, but when the second half of the ticket is printed achange must be made in It should now read: Good for one fare to Dayton from. This change in the adjustment of the type must be made while the machine is in operation, as it is necessar to make the change after the first ticket as been printed and before the second ticket is printed. This is accomplished as follows: It can be seen from Figs. 14 and 17 thatthe lower electroroller 113 is provided with a transverse shaft 220 which carries two type wheels 221 and 222. Each of these type wheels has four type faces thereon, these faces having the words from and to alternately formed thereon. These type wheels are adapted to project through openings 223 in the periphery of the roller in line with the name of the issuing station, which in this. case is Dayton. It can be seen from Fig. 17 that the type are set to print the last half of a round trip ticket, that is, the rinting will read to Dayton from. In or er to chan 'e the setting of the two type wheels 221 and 222 from a one way to a round trip setting, or vice versa, it is only necessary to rotate the shaft 220 a one-quarter turn. When one "way tickets are printed the upwardly extending portion of the lever 179 is in the osition shown in Fig. 14. This portion of t e lever carries a pin 224 which cooperates with a slot in the upper end of an arm 225 fast on a shaft 226 supported by the machine side frames. Also fast von this shaft are a plurality of arms 227, one for each of the elect-rorollers 113. The arms 227 each have an upwardly extending tooth 228 which may be moved into the ath of a four toothed member 229 fast on t e shaft 220.

When one way tickets are to be issued the mechanism is in the position shown in Fig. 14, in which the tooth 228 is not in the path of the member 229 and therefore the adjustment of the type will not be changed. When however a round trip ticket is to be printed the lever 177 is rocked clockwise, and this movement will, through the arm 225 and shaft 226, rock all of the arms 227 upwardly far enough toposition the teeth on these arms in the path of the members 229. Only one of the units of course will operate, but all of the arms 227 are rocked. The impression on the first half of a round trip ticket is taken at the very beginning of the operation, as can be seen from the shape of the cam 142 in Fig.7. After the first impression is taken and the electroroller 113 moves about one-fourth of its revolution, the tooth 228 will come into contact with one of the teeth of the member 229 and will rock this member a quarter turn in a counterclockwise direction, as seen in Fig. 14. This movement will reverse the adjustment of the to and from type so'that when the second half of'the round trip ticket is printed the wording will read correctl After the second im ression is taken, t e to and from' type wiieels will be given another quarter turn during the second rotation of the electroroller 113, which will return the type wheels to a position to print a one way ticket on the next operation. The shaft 220 and the type wheels carried thereby are flexibly held in their adjusted positions by means of a spring-pressed pawl 230 (Fig. 7 which cooperates with a squared member ,231fast on the shaft 220.

Round trip lever interlock.

Means are provided for preventing the release of the machine unless the roundtrip lever 17 7 is in either its one way or itsround trip position. This mechanism also functions to prevent movement of the lever, after the machine has been released. In order to accom lish the above mentioned functions the fo lowing mechanism is provided. The lever 177 has a rearwardly projectin tail 280 (Fig. 14) A plate 281 having its lower end bent at right angles is pivotally mounted on a stud 282 projecting from the machine side frame. This plate has an upwardly extending portion 283 in which a slot 284 is formed. The link 171, previously described, carries a pin 285 which projects through the slot 284 in the upwardly extending portion 283. It is evident from Fig. 14 that when the machine is released the link 171 moves upwardly, which movement will cause the plate 281 to rock counter-clockwise about the pivot 282. If the round trip lever is not in one or the other of its normal positions, it is apparent that the horizontal contact with the end of the tail 280, thus preventing the release of the .machine.

Date-setting mechanism Each unit of the machine is rovided with type wheels for printing the ate, and means are provided for manually adjusting .bent portion of the plate 281 will come into the corresponding type wheels in each group simultaneously, no matter how many groups 1 may be included in the machine. Each unit of the machine has a type, wheel 235 (Fig.

18 for printing the name of the month, and

two type wheels 236 and 237 for printing date. of the month. The year is not printed. The train of mechanism for setting up the units type wheel for the day of the month. will be first described. Fast on a sleeve 241, supported on a shaft 238 are a plurality of gears 239 (Fig. 18), there being one of these gears for each of the ticket issuing units. An opening 240 is provided in the cabinet (Fig. 7) through which the left hand one of the gears 239 can be manually adjusted. As each of the gears 239 is fast on the sleeve 241, the adjustment of the left hand one of these gears will of course be gears 246,

' ty e wheels 237 is fastened. Fast to the si e of the gear 242 for the left hand unit is a wheel having numbers corresponding to the type wheel 237 engraved thereon. This wheel may be viewed through an opening 247 (Fig. 7) in the casing of the machine so as to facilitate the correct adjustment of the typie wheels.

he tens of the days of the month type wheels are set up as follows: A gear 248 (Fig. 18), loose on sleeve 24]. meshes with a gear 249 which is pinned to the shaft 243.

his gear also has anindicating wheel fast thereto, as was described above. Also fast on the shaft 243 in each of the ticket'issuing units is a corresponding gear 249. Each of these gears 249 meshes with a gear 250 loose on the shaft 245 and these gears 250 mesh with gears 251 which have the tens type wheels 236 fast thereto. It is apparent from the above that the adjustment of the gear 248 will simultaneously move all of the tens tygje wheels 236 to any desired position.

he mechanism for adjusting the name of the month type wheels in each of the units is similar to that above described. A gear 252 loose on sleeve 241 meshes with a gear 253, to which is fast an indicating wheel 254 loose on the shaft 243. The gear 253 meshes with a gear 255 fast on the shaft 245. Also fast on this shaft are corresponding gears 255 appropriate to each unit, and these gears in turn mesh with gears 256, to which are fast the name of the month type wheels 235. Therefore the adjustment of the gear 252 will simultaneously set up the name of the month type wheels in all of the units.

Grand total consecutive number counter.

In addition to the consecutive counters carried b each of the destination devices each mac iine, no matter how many units may be included in its organization, is provided with a single grand total consecutive number counter which is automatically operated on every operation of the machine, no matter what destination deviceor which ticket issuing unit is operated. The counter consists of a plurality of adding wheels 260 (Fig. 6) loosely mounted on ashaft 261 supported between the rear frame of the machine and a bracket 262. The counter itself is of very conventional design and it is not thought to be necessary to give any detailed description thereof. The mechanism for operating the counter consists of a driving pawl 263 (Fig. 2) which cooperates with a ratchet wheel 264 with which it is held in engagement by a s ring 265. The driving pawl is pivoted to tile upper end of a link 266 which at its lower end is pivotally connected to a lever 267 loosely mounted on the shaft 75. At its opposite end the lever 267 carries a roller 268 which cooperates with a cam groove 269 (Fig. 5) formed in a disk 270 fast on the shaft 90. It will be remembered that the shaft 90 receives a complete clockwise rotation (Fig. 5) on every operation of the machine, and therefore due to the sha e of the cam groove 269 the lever 267 will lie rocked first counter-clockwise and then clockwise to its normal position, which will first raise and then lower the link 266. This movement of the link 266 will cause the driving pawl 263 to cooperate with and rotate the ratchet wheel 264 one step. Retrograde movement of the counter wheel is prevented by means of a spring-pressed retaining pawl 271 which is pivoted on a shaft 272, also supported by the bracket .262 and the frame. The transfer mechanism for this counter is of the well known Geneva plate type, and it is not thought to be necessary to give any description thereof herein.

Ribbon feeding and reverse mechanism.

Novel mechanism is shown herein for feeding the ink ribbon a short distance on every operation of the machine, and for automatically reversing the direction of feed of this ribbon when theribbon wound on either of the spools has been completely exhausted. The ink ribbon is wound from a spool 290 (Fig. 19) and passes from this spool about a rod 291, then about a second rod 291 (Fig. 18), and finally to a duplicate of the spool 290. The spool 290 and its duplicate spool onthe opposite side of the machine are each fast on a shaft 292 which is supported at one end by a bracket 293 mounted on the machine side frame. The opposite end of each shaft 292 is supported by a cross by the side frames. Fast on each of the shafts 292 is a spiral gear 295. Meshin with the left hand spiral gear 295 is a spira l gear 296 (Figs. 18, 19 and 20) which is loose on the shaft 238. Meshing with the spiral gear 295, on the right hand side of the machine, as seen in Fig. 18, is a spiral ear 297 which is fast on the shaft 238. ecured to the spiral gear 296 is a gear 298, and just adjacent the gear 298 is a duplicate ear 299 which is fast on the shaft 238. It is evident that when the gear 299 is driven movement will be transmitted through the shaft 238 to the spiral gear 297, which in turn will'drive the right hand one of the spiral gears 295 and cause the ribbon to be wound on the right hand spool. On the other hand, when the gear 298 is driven, the gear 296, which is fast thereto, will receive frame 294, which is also supported a like extent ofmovement, and this movement will be transmitted directly to the left hand one of the spiral gears 295 andwill cause the left hand ribbon spool to be turned is pivoted an arm 301'. The arm 301 carries two triangular shapedpieces 302 and 303. These two pieces are In the form of equi-lateral triangles secured together with their points diametrically opposite each other. The piece 302 is adapted to cooperate with. the gear 298, and the piece 303 with the gear 299. Both pieces are flexibly held against rotation by means of a retaining pawl 304 which is held in engagement with both of the triangular pieces by means of a spring 305 stretched between a pin on the pawl and a hook formed on the member 300. It is evident "that when one of the angles of either of the triangular pieces is in engagement with the teeth of its corresponding gear the. flat side .of the other piece will be in line with its gear, and therefore only one of the gears 298 and 279 can be rotated at once.

The arm 301 carries a pin 306 which normally'lies just behind the inclined bent end 307 of a lever 308 which is pivoted to the side frame of the machine. The lever is held in contact with the hub 309 of the member 300 by means of a spring 310 (Fig. 19).

Pivoted to the member 300 is one end of a. link 311 which at its opposite'en'd is pivoted to a lever 312 loosely mounted on a stud .313 projecting from the side frame. The

lever 312 carries a roller 314 which projects into a cam groove 315 out in a cam disk 316 fast on the main drive shaft 90. It is evident from Fig. 19 that upon the rotation of the cam disk 316 the lever 312 and the link 311 will be moved upwardly and then downwardly to their normal positions. Upon the upward movement of the link 311 the member 300 will be rocked counter-clock wise about the shaft 238 and the point of whichever one of the triangular pieces 302 and 303 is in engagement with its gear 298 or 299 will rotate said gear and cause the ribbon to be fed in one direction.

Upon the return movement of the link 311 and member 300 the pin 306 will strike the inclined bent end 307 of the lever 308 and will rockthe arm 301 clockwise about its pivot a sufiicient distance to raise the triangular members out of engagement with the teeth of the gear 298 or 299. As the member 300 continues its clockwise movement thepin 306 will pass over the inclined end 307 of the lever 308 and will drop be hind it, as shown in Fig. 19, which will once and p aces of like nature.

298 and 299,a tension is placed on the rib bon and the gear being .driven is held. Therefore as the arm 300 rotates the triangular ieces will be rotated on their axis, forcingt e retaining pawl 304 clockwise out of engagement therewith. As soon as this pawl passes over the point of the triangular piece with which it engages it will be pulled counter-clockwise (Fig. 19) by the spring 305 in between the next two points of the triangularpieces. This movement will re-. verse the position of these pieces with respect to the gears 298 and 299 so that the gear which was last driven will be idle and the one which was idle will be driven. It is evident that this will reverse the direction of the feed of the ink ribbon.

Mechanism for controlling the number of cycles of operation.

In Figs. 22 to 26, inclusive, mechanism is shown whereby this machine may be easi-' 1y ada ted for use in'theater ticket ofiices The ticket issuing mechanism is the same as above described. The additional mechanism shown in these figures is for the urpose of controlling the number of cyc es of operation and thereby the number of tickets issued.

The machine is released by the depression of the selected one of the detachable devices 30, which are adapted to print the price of the ticket and any other desired ,data thereon. The depression of the selected device 30 will, through its proi'ecting pins 60, rock the arms 62 counter-c ockwise (Fig. 22). Fast to the left hand one of the arms 62 is a member 330 which carries a pin 331 projecting through a cam slot 332 in a lever 333 pivoted on the shaft 75. It is evident that when the member 330 is rocked counterclockwise the pin 331, due to the shape of the cam slot'332, will rock the lever 333 clockwise. Loose on the shaft is a yoke 334 which extends across the machine and cooperates with downwardly projecting portions 335 on each'of the levers 333. A forwardl extending portion of the lever 333 has a beveled end 336 which cooperates with cylindrical members 337 sli'da'lily mounted pressed, and the lever 333 isv rocked clockwise, the beveled end 336 of this lever will engage between two of the cylindrical members 337 and cam them laterally a sufficient distance to permit the lever to enter the opening between them. Thelateral movement of these cylindrical members is limited to the extent of the width of one of the levers 333, and therefore if one of these levers has been rocked between two of the members 337 it is evident no other detachable device may be depressed, as its lever 333 cannot be rocked.

Integral with the yoke member 334 is an arm v339 which carries the lever 186 previously described. Thislever has a hook at its lower end which normally engages beneath the pin 187 carried by the arm 181. This arm 181 cooperates with the teeth of the ratchet wheel 180 fast on the shaft173. A torsion spring 195 is wrapped about the shaft 17 3 and tends to rotate this shaft in a clockwise direction, but this movement is normally prevented by the engagement of the arm 181 with the ratchet wheel 180. When one of the detachable devices is depressed, however, yoke member 334 will be rocked clockwise by the projecting portion 335, and this will cause the lever 186 to raise the arm 181 out of engagement with the ratchet, thereby permitting the ratchet and the shaft 173 to rotate in a clockwise direction until it is stopped in a manner which will hereinafter be described. 'When the shaft 173 is permitted to rotate, an arm 340 carried thereby, which normally cooperates with a pin 341 (Fig. 23) carried by an arm 172 loose on the shaft 17 3, is moved out of the path of the pin 141 and permits the arm 172 to rock clockwise. The arm 172 is connected by a link 171 with the arm 170 fast on the shaft 80. This shaft 80 is rotated clockwise upon the depression of any one of the detachable devices in a manner previously shown and described herein, and when this occurs, the arm 82 as shown in Fig. 15 will be moved out of the path of the flattened stud 83 carried by arm 84 and thereby, through the arm 86, the motor clutch will be released which will cause the machine to be operated.

The machine, in its adaptation to use in theater ticket oflices, is adapted normally to issue a single ticket, and this will be accomplished in the following manner: Fast on the shaft 17 3 are aplurality of stop arms 342. When the shaft 173 is released, and is rocked clockwise (Fig. 24) by the spring 195', the right hand one of these stop arms 342 will come into contact with the end of an arm 343 which is fast on the shaft 282 previousl described. I Also fast on the shaft 17 3 is a ate 344 which has arms 345 formed at equa distances about its periphery. It will be recalled that near the end of the operation of the machine the pin 190 carried by the disk 189 will have been moved to a position in which it will cooperate with one of the arms 345 on the plate 344. As the disk continues its rotation to its normal position, the plate 344 will be rotated counterclockwise to its normal position, where it will be held by the engagement of the arm 181 withthe ratchet 180. The pin 190 has earlier in its rotation come into contact with the surface 191 of the lever 186 and rocked this lever so as to permit the arm 181 to dro down into contact with the ratchet un er the influence of the spring 188. It is clear that as the shaft 173 is rotated countor-clockwise to its normal position, the arm 340 will engage the pin 341 and, through the link 171, rock the shaft 80 and arm 82 counter-clockwise, thereb camming the arm 84 counter-clockwise an bringing the arm 86 (Fig. 15) once more into engagement with the plate 87 on the motor clutch, and thereby stopping the movement of the driv ing mechanism after a single cycle of operation.

The present machine is adapted to issue from one to six tickets on a single operation and therefore, if more than one ticket is to be issued, it is necessary to provide mechanism which will permit the machine to continue its operation throughout a plu rality of cycles, in order to issue the required number of tickets. In order to accomplish this result applicant has provided five depressible keys 346. (Figs. 22 and 25). These keys are evenly spaced apart across the top of the machine and carry digits on their upper faces to indicate the number of tickets, the issuance of which they control. At its lower end each of the keys is pivoted to a lever 347 loose on a shaft 356 supported by the machine side frames. The keys are normally held in their undepressed positions by means of springs 348 stretched between the levers 347 and lugs on the base of the machine. On their rear ends the key levers 347 carries a block 349 which, when the key is depressed, is adapted to cooperate with a hook member 350 extending downwardly from the shaft 282. It is apparent that as the key is depressed the hook member 350 will be rocked clockwise until the block 349 has passed by a shoulder formed on the hook member, whereupon it will be returned toits normal position by means of a spring 351 (Fig. 22) which is stretched between an arm 352 fast on the shaft 282 and a pin on the side frame, and constantly tends to rock the shaft 282 in a counter-clockwise direction. When the block 349 has passed the shoulder on the hook 350 the key will be held in its depressed position.

There is one of the stop arms 342 pinned to the shaft 17 3 opposite each of the blocks 349 carried by each of the keys 346, and it can be seen from Fig. 24 that when no key is depressed the blocks 349, while in the Ion each of plane of their rotation will continue until particular stop arms, are not in the path thereof. However, when a key is. depressed and the rear end of the key lever 347 moves upwardly, the block 349 thereon will be brought into the path of the corresponding stop arm 342. It can also be seen from Fig. 24 that when a ke is depressed and through the hook mem Ter 350 the shaft 282 is rocked clockwise, the stop arm 343, which controls the machine on sin 19 ticket issuing operations, will be roc (ed downwardly out of the path of the first stop arm 342. Then, when the arm 181 is raised out of engagement with the ratchet 180 by the depression of one of the detachable devices 30 and the shaft 173 is rotated clockwise by the spring 195, this the stop arm corresponding to the key depressed comes into engagement with the block 349 carried by its corresponding key. It is evident therefore that the shaft and the stop arms carried thereby may be moved from one to six spaces, depending upon the key depressed. v I

The machine will be operated as above described and, as the pin 190 carried by the disk 189 nears its home position on the first cycle of operation, the pin will cooperate with one of the arms 345 formed in the plate 344 and will rotate this plate and the shaft 173 one space in a counter-clockwise direction toward its normal position. It is evident that each succeeding rotation of the disk 190 will cause the shaft 173 to be rotated'counter-clockwise one step until the arm 340 strikes the pin 341, and on the last cycle of o eration rocks the arm 86 (Fig. 15) into t e path of the plate 87 on the motor clutch and sto s the machine.

Means are. provide for releasing the depressed keys on the last cycle of operation of the operating mechanism. The link 171 carries a bell crank lever 353 pivoted thereto which is normally held in contact with the teeth of a ratchet wheel 354 pivoted to the-side frame of the machine. This ratchet wheel has its teeth formed with a. rounded contour which will cooperate with an up wardly extending portion 355 of the arm 352 previously described. When the machine is released, the link 171 is moved up wardly as above described, and when this occurs, thebell crank 353 is carried therewith a distance sufiicient to cause the lower end of the bell crank lever to engage the next higher tooth of the ratchet 354. Then when the link 171 is lowered during the last cycle of operation the bell crank lever 353 will rotate the ratchet wheel 354 in a clock wise direction and this movement, due to the peculiar shape of the teeth of the ratchet, will rock the arm 352 and thereby the shaft 282, in a clockwise direction. As all of the hook members 350 a re fast to the depressed (Fig.- 24) it is evident that the clockwise movement thereof will rock them out of engagement with the rear ends of the key levers 349 which will permit the springs 348 to return the depressed key to its normal undepressed posltion.

The interlock previously described with regard to the lever 179 has been adapted for use with the key levers 347. The right angle plate 281 is carried by an arm 283 loose on the shaft 282 and has a bifurcated end cooperating with the roller 285 supported by the link 171. The plate 281 is made sufliciently wide to cooperate with all of the key levers .347. It is evident that when the link 171 is raised upon the release of the machine the plate 281 will be rocked above any of the key levers 347, which have not been moved by the depression of their corresponding keys, and will therefore prevent any such movement thereof until the link 171 is again lowered during the last cycle of operation. The plate 281 will also pass beneath the end of the key lever 347 of the key which will prevent the release of this key until the last cycle of operation of the machine.

Manually controlled Zoe/c devices.

shaft 282 for detachable Means are provided in this machine for locking the machine after a destination de- Vice has been inserted in order to prevent its withdrawal, or to lock the machine against the insertion of one of the devices. This feature is especially valuable in theater ticket machines, for the operator to issue any tickets except such as are properly printed with the correct price. The member 330 appropriate to each of the ticket issuing units has an upwardly extending arm 360 carrying a pin 361 projecting through a bifurcated portion 362 of a member 333 pivoted on the shaft 238 supported by a sub-frame 365. Also supported by this sub-frame is a cylinder lock 366 of conventional design. The key barrel 367 of this-lock liesjust beneath an opening 368 in the cabinet of the machine. When a key is inserted into the key barrel 367, and rotated therein, will move a bolt 36.9"to either, its looking or unlockingposition, as desired. The bolt is adapted to cooperate with a projecting portion 370 of the member 363.

It can be seen from Fig. 22 that with a detachable device inserted in the machine, in the position shown in this figure, the projection 370 of the member 363 will lie below the bolt 369. If, after a detachable device is inserted to this position, the bolt 369 is moved by its appropriate key, the bolt will assume a position below the projection 370 and thereby prevent the withdrawal ofthe' detachable device fromthe machine, but will the lock mechanism I
